" (v) "(cos150^(@)+i sin150^(@))/(cos60^(@)+i sin60^(@))

Write down the following complex number in polar form: Quotient of 12(cos150^(@)+i sin150^(@)) and 3(cos60^(@)+i sin60^(@))

The value of (cos 30^(@) + i sin 30^(@))/(cos 60^(@) - i sin 60^(@)) is equal to

Divide 12 (cos 150^@ + i sin 150^@) by 3 (cos 60^@ + i sin 60^@) .

cos 60^(@) sin 30^(@) +cos 30^(@) sin 60^(@)=
